Guys - a rad alt minimum is only valid if the terrain before the runway is reasonably flat. There is no way a radio DH would have been published for that runway. If they used one, they made it up and suffered as a result..
Maybe I wasn't precise enough. Used to call DH the settings on AN/APNs. In Russian and in Polish those two different DHs have distinctive names. Anyway, again.
The decision height was 100 m, but according to Tu-154M FM you have anyway to set a rad alt minimum, which is equal to the DH, if DH < 60 m or you have to set it to 60 m, if DH => 60 m. If no runway lights visible passing rad alt minimum, it's missed approach.
Hope this time it's OK.
